(2) Return to thefirst road junction. Take the gravel path on the right that leads downhill. Join the path that leads to the Château de la Serraz.

(3) Here you can make a round trip to the castle. Continue on and you will come out at the edge of the forest at a place called Verdex. Pass in front of the school. Continue on, keeping to the left at the crossroads. You will reach the Grangeons neighbourhood.

(4) Leave the road and climb up to the hamlet. Take the grassy path until you reach the road again. Turn left and follow it to rejoin Chemin des Ciseaux.

A lovely route with superb views over the Aix-Chambéry valley. The finish at Ombrosa School is brilliant – a great spot for a picnic with a 200-degree view.
Enjoy the ride

If you enjoy walking under the blazing sun for 70% of the route, you've come to the right place! The description says it's a family-friendly, easy hike... Let's just say that it's only suitable if you leave the youngest and least fit members of your party at home. Very disappointed: not much to see overall.

Pleasant route.
Three comments:
1) It is better to follow the hiking trail from the car park overlooking the road, as it is more pleasant than walking along the road. After 2 or 3 km, take the path on the left that connects to the road to continue the walk as indicated.
2. The name of the car park is not very clear: on the satnav, follow the signs for the Garde car park.
3. There is little view of the lake; you are really at the end of the lake.

And here is another piece of missing information to report at a crossroads, which is misleading
It's a shame, otherwise it's an interesting walk.
Be careful, it's quite steep at the beginning, so a walking stick is very useful.

Can be done starting from Les Ciseaux, which allows you to start the climb at the beginning of the walk.
However, there is limited parking.

too much tarmac road
the car park is the police station car park
to avoid the tarmac at the car park, take the path behind the notice board and then the first path on the left, which takes us back to the antenna before the St Alban rock

A very pleasant hike offering a different view of Lake Bourget.
Just one comment regarding the section off the IGN trail, where it is easy to get lost.

My disappointment stems from the fact that too much of the route is on tarmac roads, which, given the location, are quite busy! It would have been possible to take the very passable path parallel to the road from the car park! This path leads right to the antenna at the entrance to La Roche St Alban and is easy and wide. It doesn't add any distance and avoids a long stretch of tarmac road!
Otherwise, the second part begins in the forest, which is refreshing in hot weather!
The crossing of the upper part of Bourget du Lac is pleasant, and the view of the lake and mountains is very enjoyable.
The small waterfall at point 6, very close to the path, is very pretty, which makes up for the fairly steep climb in this section, but fortunately it is short!

The location of the car park wasn't clear, but luckily we were able to find it using the app and Map. After the chapel in paragraph 2, we had trouble finding the first road, as it seemed to only serve houses. But overall, it was a good walk. It would benefit from more signposts, perhaps something for the tourist office to look into.

An easy and pleasant walk. However, at point 1.2, I would suggest: Go to the chapel.
Return to the car park, then take the gravel path on the right that descends between the car park and the houses.

The beginning and middle of the hike are quite pleasant as you walk through the woods. But the road section is less interesting. Unfortunately, I couldn't enjoy the view as it was raining and we were in the clouds that day. Otherwise, I'm sure the view of the lake from the road must be very nice.
